Week 15 Discussion

After completing the reading this week, we reflect on a few key concepts this week:

Discuss Howell and Mendez’s three perspectives on follower-ship. Note how these behaviors influence work productivity.

What is the big five personality model?

What is the Myers-Briggs test? How is it similar to the Big five model? How is it different than the Big five model?

Please be sure to answer all the questions above in the initial post.

Please ensure the initial post and two response posts are substantive. Substantive posts will do at least TWO of the following:

Ask an interesting, thoughtful question pertaining to the topic

Expand on the topic, by adding additional thoughtful information

Answer a question posted by another student in detail

Share an applicable personal experience

Provide an outside source

Make an argument

At least one scholarly (peer-reviewed) resource should be used in the initial discussion thread. Please ensure to use information from your readings and other sources from the UC Library. Use APA references and in-text citations.

Operations Security – Risk management policies

Scenario :

“You arrive at work on Monday morning to discover that your computer is not working properly. It stops responding and restarts every few minutes. Unexpectedly, you see unusual error messages popping up and hear some strange sounds from the speakers.”

Discussion Question:

• What is the first possible diagnosis that comes to your mind?
• What is the first step you would take in this situation?
• What is the second step that you would take in this situation?

One and half page is fine

Managing Risk

Your company has decided to implement a human resource demographic portal.  Under the system envisioned, employees would be able to use an online internal web page to change various personal information items themselves, such as, address phone, etc.  In addition, the employees would be able to change limited payroll related items, such as 401k deduction percentages or amounts, optional United Way contributions, and the number of federal and state exemptions to be claimed. Along with thie portal would be the ability to view, download, and print current and YTD pay information, including the current paycheck and check “stub”.  

Under the current system, employees must go to the HR office to make any changes – there is no online access.

Your company already requires direct deposit for all employees, and under the new system, pay stubs would no longer be printed.  Employees would be able to do this as needed through the portal.

 There are many potential risks associated with this project. 

1. Your task is to Identify as many risks as you can (4 is a minimum, but feel free to identify more risks if you so desire).
2. Determine the relative likelihood of each risk occurring (low, medium high)
3. Propose at least one strategy for addressing each risk, and describe the strategy in terms of the 4 risk responses (Avoidance, Transference, Mitigation, or Acceptance).

Remember that sometimes, risks are acceptable and can be taken, so long they are identified and a strategy to address the risk is presented.  For example, driving a car is a risky venture, but to address that risk we have driver’s education (mitigation), manufacturing safety standards (mitigation), insurance (transference), and staying at home (avoidance). Driving an older, unsafe vehicle by an unlicensed and uninsured motorist could be considered acceptance,

.

Turn in as much as needed. (Sometimes less is more, sometimes more is more; it’s your call.)

Support your strategies as needed with external references, and make sure your answer directly address the potential risks with the  human resource demographic portal.

This week’s reading centered around how Big Data analytics can be used with Smart Cities. This is exciting and can provide many benefits to individuals as well as organizations. For this week’s research assignment, you are to search the Internet for other uses of Big Data in RADICAL platforms. Please pick an organization or two and discuss the usage of big data in RADICAL platforms including how big data analytics is used in those situations as well as with Smart Cities. Be sure to use the UC Library for scholarly research. Google Scholar is the 2nd best option to use for research.Your paper should meet these requirements:

• Be approximately four to six pages in length, not including the required cover page and reference page.
• Follow APA 7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.
• Support your answers with the readings from the course and at least two scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. The UC Library is a great place to find resources.
• Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.

weekly log for it project

Update (10/24): 

• The file hashtable.py has been updated and now includes some code to get started with unittest (go to MS Teams to download it).
• You will want to download hashtable.py and add onto it, rather than importing it from a new file you create (since you won’t be able to extend the class across separate files).
• Yes, there is some redundancy between unit tests and the file test_hashtable.py. I am using test_hashtable.py in order to both test and interact with your class (more easily). If your unit tests are thorough/comprehensive, then it will likely look similar to the final version of test_hashtable.py that I will use. 

The tasks in this assignment are to extend the HashTable class that is currently defined in the file “hashtable.py” (located in MS Teams -> General -> Files -> Code). 

By extending it we will increase the functionality of the HashTable class (by adding more methods) and will make it more flexible (e.g. can resize itself as needed) and robust (e.g. no issues/errors when it is full and an item is added). 

The ways to extend the class, and thus the requirements for this assignment are as follows. 

1. Override Python len() function to work with HashTable in a specific way – Using def __len__ will override the Python len() function. The way this is implemented should be to return the number of items stored in the hash table (note: this is *not* the same as HashTable’s “size” field). 

2. Override Python in operator – This will be done using def __contains__ and should be implemented so this operator will then return a boolean when used in statements of the form  54 in myhashtable. For this example, the function should return True if 54 is an existing key in the HashTable instance myhashtable, and False if it is not. 

3. Override Python del operator – This is done by  using def __delitem__ and should allow for a key/value pair to be removed from an instance of HashTable (e.g. del h[54]). Think about how you want to handle cases when deleting a key that was involved with collisions. Be sure to include in the documentation for this method any assumptions/restrictions on how this can be used. 

4. Modify exiting put method to resize an instance as needed – The current HashTable implementation is limited in that it is not able to gracefully handle the case when an item is added to already full HashTable instance. This method should be modified to deal with this more gracefully, and should resize the instance for the user. Be sure to include documentation here describing exactly when you choose to resize and how you select an appropriate new size (remember that prime numbers are preferred for sizes, in order to avoid clustering, or an even more severe but subtle issue). 

All of those methods should be clearly documented to describe how and why the implementation is defined as it is. You will also want to use unittest on this assignment. One good use case for unittest will be to add a few items (and maybe even delete) one, and then to use unittest to verify that the slots and data fields are equal to what you expect. All of the extensions that you’ve added should be tested as well.  

Lastly, for grading, you will want to ensure that you’re program can be run through a test script. The test script will look like the code shown at bottom of this assignment description. When it is run we should expect output similar to what is shown in this screenshot.

test_hashtable.py (the final test script will vary slightly from this):

from <> import HashTable

# instantiate a HashTable object
h = HashTable(7)

# store keys and values in the object
h[6] = ‘cat’
h[11] = ‘dog’
h[21] = ‘bird’
h[27] = ‘horse’

print(“-“*10, “keys and values”, “-“*10)
print(h.slots)
print(h.data)

# check that data was stored correctly
print(“-“*10, “data check”, “-“*10)
if h.data == [‘bird’, ‘horse’, None, None, ‘dog’, None, ‘cat’]:
    print(”    + HashTable ‘put’ all items in correctly”)
else:
    print(”    – items NOT ‘put’ in correctly”)

# check that ‘in’ operator works correctly
print(“-“*10, “in operator”, “-“*10)
if 27 in h:
    print(”    + ‘in’ operator correctly implemented”)
else:
    print(”    – ‘in’ operator NOT working”)

# delete operator
del h[11]

# check that len() function is implemented and works
print(“-“*10, “len() function”, “-“*10)
if len(h) == 3:
    print(”    + ‘len’ function works properly”)
else:
    print(”    – ‘len’ function NOT working”)

# “in” operator (returns a boolean)
print(“-“*10, “len() after deletion”, “-“*10)
if 11 not in h:
    print(”    + ‘in’ operator works correctly after 11 was removed”)
else:
    print(”    – ‘in’ operator OR ‘del’ NOT working”)

# check that data was also removed
print(“-“*10, “data after deletion”, “-“*10)
if h.data == [‘bird’, ‘horse’, None, None, None, None, ‘cat’]:
    print(”    + data is correct after deletion”)
else:
    print(”    – data not correctly removed after deletion”)
